Specifications

NOTE: Buildings that are heated and/or cooled must meet the requirements of the International Energy Conservation Code in effect for the building’s final destination. If you select an insulation system that does not meet these minimum requirements, we will add insulation to meet the code when the building is quoted.

Ceiling

The metal ceiling system will consist of 3" deep, 16" wide interlocking panels of nominal 24-guage embossed galvanized steel, factory painted Arctic White. The ceiling system will be supported at its perimeter by concealed angles. The ceiling system will be furnished complete with all necessary connectors and fasteners- Option R-30:

The ceiling will be insulated with 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation laid in panel void. A 1/4" layer of continuous, reflective, polyethylene insulation (R-7.55, U-0.13) will be laid on top of the ceiling panel ribs. A second layer of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation will be laid on top at right angles to the panel ribs. The "U" value through the finished ceiling will be a maximum of 0.04 BTU’s per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition. Clear height = eave height – 6" (single slope type buildings), eave height – 9" (gable type buildings).

- Option R-38

The ceiling will be insulated with 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation laid in panel void. A 1/4" layer of continuous, reflective, polyethylene insulation (R-7.55, U-0.13) will be laid on top of the ceiling panel ribs. A second layer of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation will be laid on top at right angles to the panel ribs. A third layer of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation will be laid on top, parallel to the ceiling panel ribs. The "U" value through the finished ceiling will be a maximum of 0.032 BTU’s per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition. Clear height = eave height – 8" (single slope type buildings), eave height – 11" (gable type buildings).

- Option R-49

The ceiling will be insulated with 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation laid in panel void. A 1/4" layer of continuous, reflective, polyethylene insulation (R-7.55, U-0.13) will be laid on top of the ceiling panel ribs. A second layer of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation will be laid on top at right angles to the panel ribs. A third layer of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation will be laid on top, parallel to the ceiling panel ribs. A fourth layer of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation will be laid on top at right angles to the panel ribs. The "U" value through the finished ceiling will be a maximum of 0.025 BTU’s per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition. Clear height = eave height – 11" (single slope type buildings), eave height – 13" (gable type buildings).

Blanket Roof Insulation

Roof insulations will consist of 48" wide, 3" thick, 6# density fiberglass faced on its exposed side with a white metalized polypropylene scrimkraft facing. The faced insulation material will have a UL Flame Spread Rating of 26 when tested in accordance with UL 723 ASTM E procedures. Insulation will be supported at the roof line by means of mechanical clips spaced on maximum 4’-0" centers and will be sealed by means of 2" side tab on facing.

Therma-Roof

The Therma-Roof insulation system will consist of two layers of 1-1/2" thick, 48" wide polyisocyanurate foam board faced with a white embossed foil on the exposed interior surface. The roof insulation system will include metal supporting tees on 4’ centers and all trim required for a finished interior appearance. No metal-to-metal contact between the insulation system and exterior roof or wall covering will be permitted. The insulation will have a maximum UL flame Spread Rating of 25, Fuel contributed Rating of 10 and Smoke Developed Rating of 155-190 when tested in accordance with UL 723 testing methods and will meet the requirements of the Underwriters Laboratories "Wall-Ceiling" Construction Classification.
